Scott, I am at about the same place as you with my '38 also going on a Dakota. I have not relocated the rear springs yet. I am also close to welding in the radiator support. I did like you and put the front fenders on to locate the body over the front wheels on the Dakota frame. I have trimmed a little off the front frame rails, but only enough to get the fenders on. After the radiator support is in place I will be able to take several inches more off of the front rails. Have you decided how you are going to attach the body to the Dakota frame? I still have the '38 frame and have considered cutting the original body mounts off of it and making brackets to weld them onto the Dakota. Or, maybe look for aftermarket body mounts to weld on?
